If an interrupt arrives while the create\npath holds the plain xa_lock, the lookup spins forever trying to\nacquire the same lock.\n\nUse IRQ-safe XArray helpers for all QP and CQ create-path updates,\nincluding the GSI QP store and error paths. Initialize both arrays with\nXA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state."
